Disclosed is a process for the industrial synthesis of Lurasidone from (1R,2R)-cyclohexane-1,2-diyldimethanol (1), 3-(piperazin-1- yl)benzo[d]isothiazole (3) and (3aR,4R,7R,7aS)-3a,4,7,7a-tetrahydro-4,7- methanoisobenzofuran-1,3-dione (6).). Said process is optimised to obtain Lurasidone with high yields and high purities by preparing highly pure synthesis intermediates, using critical raw materials and reagents in amounts close to the stoichiometric amounts, increasing productivity and reducing the costs and environmental impact of the process.
揭示了一种从(1R,2R)-环己烷-1,2-二甲醇(1)、3-(哌嗪-1-基)苯并[d]异噻唑(3)和(3aR,4R,7R,7aS)-3a,4,7,7a-四氢-4,7-甲基异苯并呋喃-1,3-二酮(6)合成Lurasidone的工业化过程。该过程被优化,通过制备高纯度的合成中间体,使用接近化学计量量的关键原材料和试剂,增加生产率,降低成本并减少环境影响,以高产率和高纯度获得Lurasidone。
